The car exhaust pipe is loud and what s going on

Analyze the reason, it should not be the problem of exhaust pipe leakage, because if the exhaust pipe leaks, the higher the speed, the more obvious the sound, only when the idle speed is obvious, it is estimated that the engine is not burning very well, the mixture is too thick, and the gasoline that is not completely burned enters the exhaust pipe, and it is caused by deflagration in the place where the temperature in the front of the exhaust pipe is higher. Generally, there are many reasons for poor combustion, such as poor ignition of spark plugs, more carbon deposits in the inlet tract, poor atomization of fuel injectors, ignition timing deviation, etc., this fault should be specifically analyzed, read the data stream with a diagnostic computer, and analyze the data to determine whether it is ignition, or fuel injection, or timing problems I hope it can help you

It should be caused by the combustion of the engine when it is not very good, the mixture is too thick, and the gasoline that is not completely burned enters the exhaust pipe and deflagrates at the place where the temperature in the front section of the exhaust pipe is high. Generally, there are many reasons for poor combustion, such as poor ignition of spark plugs, more carbon deposits in the inlet duct, poor atomization of fuel injectors, ignition timing deviation, etc., this fault should be specifically analyzed, read the data stream with a diagnostic computer, and analyze the data to determine whether it is ignition, fuel injection, or timing problems.

Gasoline combustion is not sufficient, and it is easy to occur just after starting.

It is estimated that it should be that the combustion is not very good when the engine is working.

Check if there is anything wrong with the ternary in the tail throat.

Causes of loud exhaust pipes:

1. If the sound is very loud and obvious, it means that the exhaust pipe is very likely to be discharged, and the exhaust pipe is discharged, that is, the fuel is burned in the exhaust system, resulting in an occasional sudden increase in exhaust pressure, and a sudden sound occurs, which may be caused by the engine ignition advance angle is too small; The mixer is too thin and is not successfully ignited in the cylinder; The mixture is too thick, and it is not successfully ignited in the cylinder, etc.

2. When idling, the engine speed is low, and the airflow speed of the exhaust system is fast and slow, if the sudden sound is not very loud, it is normal.

3. Severe idle jitter accompanied by a serious sudden sound, which needs to be checked.

If it is not repaired in time, it is likely to cause some bigger problems, and if it causes bigger problems, it is not only about repairing these exhaust pipes, so when your car exhaust pipe encounters some problems.

It can be repaired in time, or it can be modified, so that it looks more convenient and time-saving, and many parts of each car are very important, and every car, every small part is quite important.

If the car is very loud, the biggest possibility is that the exhaust pipe is damaged or aging and corroded, if it is found that the exhaust pipe is aging, it should be replaced immediately.

Cars have become a necessity in people's lives, and many of us attach great importance to cars, but now many people have a lot of problems on the car, more or less including some details of the problem, we must pay attention to the safety performance of the car, if the body is abnormal, do not continue to drive forcefully to avoid accidents.

Automobile exhaust bellows, also known as automobile exhaust hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, so as to play a role in vibration and noise reduction, convenient installation and prolonging the life of the exhaust noise reduction system.

There are reasons why the sound is loud, that is, look at the loud sound, some are modified sports cars, some are loud, some things are changed to the sound of the strong and powerful, and there are also things that the exhaust pipe has been rusting for a long time, broken, rotten, and there will be loud sounds.

It should be caused by a leak in the exhaust pipe or damage to the inside of the muffler.

If there is a leak in the exhaust pipe, or the interface is not in good contact, find a repair shop to lift the car up and see.

There's something in it that rots over time, so it's very loud.

It should be a loophole in the exhaust pipe, most likely in the middle section.

Either the exhaust pipe is broken, or there is an air leak there.

The silencer is perforated, hope it works for you.

You can do this as follows:

Tools Required: Wrench.

1. The loud sound of the exhaust pipe is caused by the aging of the gasket at the connection between the exhaust pipe and the engine.

2. Use a wrench to remove the screws at the connection between the exhaust pipe and the engine.

3. After loosening the screws, the exhaust pipe will automatically separate from the engine.

4. After that, take the aging washer down and disassemble the washer.

5. After that, put the new gasket on the exhaust pipe.

6. Use a wrench to tighten the screws, so that the sound of exhaust shouting and grinding the lead pipe is smaller.

Summary. The exhaust pipe of this new car is relatively loud, this is a normal phenomenon, and there is no problem with this. Because when the engine of this new car is working, the sensors on the engine, including its control computer control system, do not reach a normal state.

Therefore, the engine is not working very well, it is not normal, this combustion is not very good, so it feels like the exhaust sound is a little louder, this is a normal phenomenon, there is no problem, after running for a period of time, after thousands of kilometers, or after the first maintenance, it will be restored.

The exhaust pipe of this new car is relatively loud, this is a normal phenomenon, and there is no problem with this uproar. Because when the engine of this new car is working, the sensors on the engine, including its control computer control system, do not reach a state of normal operation. Therefore, the engine is not working very well, it is not normal, this combustion is not very good, so it feels like the exhaust sound is a little louder, this is a normal phenomenon, there is no problem, after running for a period of time, after thousands of kilometers, or after the first maintenance, it will be restored.

The main sound of the pipe is loud when the fire is fired.

The moment it starts, the sound of the exhaust pipe is particularly loud, this is a normal phenomenon, every car is like this, there is no problem.

How can this be solved, or that the new car looks like this, running about 400 kilometers.

There is no way to solve this, every Qin hunger starts to take the return machine is like this, the engine speed is relatively high at the moment of starting, the sound of this exhaust is relatively large, this is a normal phenomenon, every Min shirt car is like this, this can't be solved.

It is necessary to install the engine guard.

If you don't run the mountain road, you don't run the potholes, there is no need to install it.

If there are any drawbacks to the engine after installation.

There is no impact.

It's waste oil <>

This is also this one or twenty pounds of this thing, and this one doesn't cost much oil. Basically negligible, for this fuel consumption.

Is it necessary to use the teacher's fuel treasure?

It will be used after 20,000 or 30,000 kilometers.

Hello, happy to answer your questions.

What's going on with the louder car exhaust pipes?

Hello, happy to answer your questions.

Hello, the sound of the exhaust pipe of the car suddenly became louder, this may be said to be your exhaust pipe that interface gasket is broken, and then the seal is not tight, the second word may be said to be your exhaust pipe rust through the sound becomes louder, this I suggest you go to the repair shop to raise the car, and then hit the vehicle gas pedal, the employer listens to it below to know that it is ** sound.

The heavy noise of the exhaust pipe of the car should be caused by poor combustion of the engine, too concentrated mixture, incomplete combustion of gasoline entering the exhaust pipe, and high-temperature deflagration at the front of the exhaust pipe. There are generally many reasons for poor combustion, such as poor ignition of spark plugs, more carbon deposits at the air intake, poor atomization of the injector, ignition timing deviation, etc. What causes a car exhaust pipe to be loud?

1.If it's loud, it obviously means that the exhaust pipe is likely to shoot out. Exhaust pipe targeting, that is, fuel burning in the exhaust system, occasionally leads to a sudden increase in exhaust pressure, and suddenly makes a sound, which may be caused by the engine ignition advance angle is too small; The mixer is too thin, which is caused by the unsuccessful ignition of the cylinder; The mixture is too thick, which is caused by the unsuccessful ignition of the cylinder; The cylinder is leaking, and the cylinder pressure is too low to ignite.

2.At idle, the engine revs low, and the exhaust system airflow speed is fast and slow. If the sudden sound is not very loud, it is normal.

3.The idle jitter is severe, and there is a violent abnormal noise, which needs to be checked.
